Question
If a star is moving towerds earth then the spectrum line are shifted towerds:
Options
A.yellow
B.infraed
C.blue
D.green
Solution
Red shift takes place when a star moves away from the earth. Red shift occurs due to
Doppler′s effect formed in light. The apparent frequency of light is decresed when source is going away from the observer.
Blue shift occurs when the source move toweds the observer.
